AMC has released the newest official 30 second trailer for their upcoming THE WALKING DEAD: SEASON 3 premiering Sunday, October 14 at 9pm ET/PT. It shows a bit more of the prison and brand new characters we’ll be running into.

In a world overrun by zombies, Rick Grimes (Andrew Lincoln) and his band of survivors must not only fight the dead, but also face a whole new fear: the living. While Rick and the gang are busy clearing out a prison in the hopes of transforming it into a protective fortress, not so far away is the town of Woodbury, Georgia, and its self-appointed leader/dictator, the Governor (David Morrissey). THE WALKING DEAD stars Lincoln, Sarah Wayne Callies, Laurie Holden, Steven Yeun, Norman Reedus, Chandler Riggs, Lauren Cohan, Scott Wilson, Iron E Singleton, Melissa McBride, David Morrissey and Danai Gurira. The series is executive produced by Glen Mazzara, Kirkman, Gale Anne Hurd and David Alpert with Greg Nicotero as co-executive producer.

And as an added bonus, here are 3 new stills from the upcoming season…
